Playing with more steam

Today is my second attempt with my new homemade steam vent cover and I was rather pleased with its performance. I was getting nearer the kind of grigne that is seen in Hamelman's book. The huge amount of steam resulted in a reddish glossy finish on the crust. The flaps on the grigne was more pronounced than usual. However, I feel that there's still room for improvement and I can't wait to bake another batch as I have another idea to try out.
